A new Phase I Tool is released for each semester. Information on how to
download and install the Tool is given on the semester's
installation page. Differences from previous versions
are described on the
hot news page.

observations, which are defined by
target,
instrument and instrument configuration (a wizard will lead you through a decision tree of modes and their options),
observing conditions
and observing time. Investigators should use the
integration time calculator
to determine the integration time needed for your instrument configuration, conditions and required signal to noise. Overheads should be included in the observing time request in the Phase I Tool, as described in the "Overheads" section of each
instrument's web page.
Time required for calibration should not be included unless you require calibrations that are beyond
the baseline calibrations offered for the instrument, described in the "Calibration" section of each instrument's web page.

Band 3 observations should be defined if your program can be carried out in relatively poor
conditions,
or can be adjusted to make it viable in such conditions. Information on how to make your program
viable for Band 3 is given on the
advice for Band 3 page.

Scheduling constraints if there are time-critical or synchronous observations involved, or impossible dates for classical programs.

Time request - both your total and minimum time for useful science should be specified, and also the total and minimum Band 3 time if your program is viable in Band 3. You can also choose how to distribute the time
across the partners, if this is a
joint proposal. This tab also allows you to specify whether or not the proposal contains
Targets of Opportunity (ToO)
and if so whether these are rapid or standard ToO observations.

There is a PDF attachment
which is submitted with the proposal. This attachment contains the Scientific Justification, Technical Case, an Experimental Design, a description of how a
queue program
would be carried out in Band 3 or how a
classical program would use poor conditions, justification of any duplicate observations, a publications list, and a description of the use of other facilities and previous Gemini use. Attachment of representative ITC results is encouraged. Latex and word templates are available at the Tool download site to generate the attachment, and should be used. Large and Long Programs have additional requirements.

The Tool will highlight errors in your proposal. Incomplete sections or input errors will be described by text in the lower panel. If your targets have poor visibility, the configuration is such that
guiding will be difficult, or if there are duplicate observations found in the
Gemini Science Archive, then these will be flagged in the columns on the Observations tab.

Once you are ready to
submit a single click on the "Submit this Proposal" button will send the proposal and PDF attachment to the servers of your selected partner(s). Currently submissions cannot be overwritten. Submit your corrected proposal and contact your
NGO office to let them know which proposal you want considered, and which omitted.

Successful PIs will be contacted via email around the middle of June and December, with important information regarding the completion of
Phase II. Typically the PI deadline for completing Phase II is the middle of July and January. Successful PIs will find the
What to expect once your observations are in the queue page helpful.
